Itis not necessary to have a preamp out for a Subwoofer,crutchfield sells a adapter
you just put a awg 16/wire in the + - for each side of adapter ,and either a
banana or spade into speaker terminal it is actual more accurate
and crutchfield , or call SVS subwoofers they can tell you exactly what it is called for under $30 I used one with my Krell integrated worked great.
